Abstract
The row crop cultivator includes a cultivation unit (10) with a unit frame (12) attached to a tool bar (21) by parallel links (28 and 34). The unit frame (12) is supported by a pair of gauge wheels (14 and 16). A disk coulter (18) is mounted on the unit frame (12) with its forward edge positioned between the gauge wheels (14 and 16). A middleworker (20) is supported by the unit frame (20) directly behind the disk coulter (18). The gauge wheels (14 and 16) are mounted on an axle assembly (90) that includes gauge wheel arms (92 and 94) and a force equalizing link (98). The force equalizing link (98) equalizes the force exerted on the two gauge wheels (14 and 16) by the unit frame (12). An adjustment rod (106) adjusts the position of the force equalizing link. A coulter adjustment rod (54 ) with a lost motion connection adjusts the maximum depth of the disk coulter. The middleworker (20) includes a shank attachment bar (152), a triangular horizontal plate (164) with a subsoil point (160) and two reversible shares (170 and 172).
